This Prince, brother of Philip the Fair, in 1301 had married Catharine, daughter and heiress of Philip de Courtenay, titular Emperor of Constantinople, and on the strength of this marriage had at a later date set up his own claim to the Empire of the East.  To this he was prompted by Pope Clement V., who in the beginning of 1306 wrote to Venice, stimulating that Government to take part in the enterprise.  In the same year, Charles and his wife sent as their envoys to Venice, in connection with this matter, a noble knight called THIBAULT DE CEPOY, along with an ecclesiastic of Chartres called Pierre le Riche, and these two succeeded in executing a treaty of alliance with Venice, of which the original, dated 14th December, 1306, exists at Paris.  Thibault de Cepoy eventually went on to Greece with a squadron of Venetian Galleys, but accomplished nothing of moment, and returned to his master in 1310.[8]

During the stay of Thibault at Venice he seems to have made acquaintance with Marco Polo, and to have received from him a copy of his Book.  This is recorded in a curious note which appears on two existing MSS. of Polo’s Book, viz., that of the Paris Library (10,270 or Fr. 5649), and that of Bern, which is substantially identical in its text with the former, and is, as I believe, a copy of it.[9] The note runs as follows:—­

“Here you have the Book of which My Lord THIEBAULT, Knight and LORD OF CEPOY, (whom may God assoil!) requested a copy from SIRE MARC POL, Burgess and Resident of the City of Venice.  And the said Sire Marc Pol, being a very honourable Person, of high character and respect in many countries, because of his desire that what he had witnessed should be known throughout the World, and also for the honour and reverence he bore to the most excellent and puissant Prince my Lord CHARLES, Son of the King of France and COUNT OF VALOIS, gave and presented to the aforesaid Lord of Cepoy the first copy (that was taken) of his said Book after he had made the same.  And very pleasing it was to him that his Book should be carried to the noble country of France and there made known by so worthy a gentleman.  And from that copy which the said Messire Thibault, Sire de Cepoy above-named, did carry into France, Messire John, who was his eldest son and is the present Sire de Cepoy,[10] after his Father’s decease did have a copy made, and that very first copy that was made of the Book after its being carried into France he did present to his very dear and dread Lord Monseigneur de Valois.  Thereafter he gave copies of it to such of his friends as asked for them.

“And the copy above-mentioned was presented by the said Sire Marc Pol to the said Lord de Cepoy when the latter went to Venice, on the part of Monseigneur de Valois and of Madame the Empress his wife, as Vicar General for them both in all the Territories of the Empire of Constantinople.  And this happened in the year of the Incarnation of our Lord Jesus Christ one thousand three hundred and seven, and in the month of August.”

Of the bearings of this memorandum on the literary history of Polo’s Book we shall speak in a following section.
